Key result
Total neck soft tissue volume was significantly greater in men than women (1295 vs 928 cm3, p<0.001), with men having more fat in anterior palatal segments despite similar total neck fat.
Why the study?
Are there differences in neck soft tissue and fat distribution between normal men and women that could explain the higher prevalence of SAHS in men?
Cross-Sectional (n=20)

Absolute Event Rate: 1295% vs 928%
p-value: p=<0.001
Differences in regional neck fat deposition and greater overall soft tissue loading in men may contribute to the higher prevalence of obstructive sleep apnea in men compared to women.
No takes yet. Share an insight, caveat, or question.
Neck fat distribution differences may inform OSA sex disparity; leaves open causal mechanisms for prospective study.
Whittle et al. (1999) conducted a cross-sectional in Healthy volunteers (n=20). Male sex vs. Female sex was evaluated on Total neck soft tissue volume (cm3) (p=<0.001). Total neck soft tissue volume was significantly greater in men than women (1295 vs 928 cm3, p<0.001), with men having more fat in anterior palatal segments despite similar total neck fat.
